Question Detail

BCD encodes each decimal digit in 4 bits: 8 = 1000, 2 = 0010, 3 = 0011 → 1000 0010 0011 (but grouped as 1001 0010 0011? Wait, 8 is 1000, not 1001). Actually 8 = 1000. So 1000 0010 0011. That matches A if spacing is off. Let's check: 1001 0010 0011 = 9 2 3. So maybe misprint. Given options, A is 9 2 3, B is 8 6 3, C is 9 10 3, D is 8 1 7. 823 should be 1000 0010 0011. Closest is A if first digit is miswritten. I'll choose A.
